CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 492,231, dated February 21, 1893.

Application filed May 16, 1892. $erial No. 433.118. (No model.)

To all whom it may concern.

Be it known that we, WVILLIAM RADER and EDWIN HUNTER, both of Allentown, in the county of Lehigh and State of Pennsylvania,

have invented a new and useful Oar-Axle Box, of which the following is a full, clear, and exact description.

This invention relates to improvements in car axle boxes, and has for its object to pro vide such a device with an improved sponge holder, a novel spring closer for the lid of the box, and improved means to restrain the escape of oil from the box at its inner side.

To these ends, our invention consists in the construction and combination of parts, as is hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a top' view of the box with its lid opened and parts removed on the line 11 in Fig. 2; Fig. 2 is a longitudinal section on the line 22 in Fig. 1, showing a portion of an inserted axle, and with the lid closed; Fig. 3 is a broken inner side view of the lid of the box, showing its hinge joint; Fig. 4is a transverse section on the line 44 in Figs. 1 and 2 Fig.5 is a cross section on the line 5-5 in Figs. 1 and 2; Fig. 6 is a transverse section on the line 6*6 in Figs. 1 and 2; Fig. 7 is a cross section on the line 77 in Figs. 1 and 2; and Fig. 8 is a broken sectional view of a detail of construction on theline 88 in Fig. 1.

The box body A, is preferably cast from metal,and issubstantially rectangularin form, having the commonupward apertured proj ection in front that is rabbeted at a, for the reception of the edge portion of a lid B.

As shown in Fig. 1, there are two side scrolls b, formed in the box bodyA, between whicha centerscroll c, on the lid 13, isintroduced, the perforations in these scrolls aligning when the lid is in place, permitting the insertion of a cylindrical pintle bolt d, forming a hinge joint for connection of the lid with the axle box, and to prevent a lateral displacement of the bolt two cap plates (1', are provided which are secured over the ends of said bolt as shown by dotted lines in Fig. 1.

At the inner end walls of the scrolls 1), two

similar detent disks b are formed or affixed,

having their peripheries scalloped as indicated in Fig. 2, where one disk is shown, these serving to retain the lid B, open or closed, by an engagement of their notched edges with the body of the core rod 6', that is secured at its ends and center within the scrolled end of a locking spring e, which latter is secured to the lid B, and projects its scrolled portions therefrom as shown in Figs. 2 and 3.

It will be seen that by the described construction of parts, the resilient body of the locking spring e, will allow the core rod 6 to rock from one scallop notch to another on the detent disks b, and thus retain thelid at different points of open adjustment or hold said lid in a closed condition as represented in Fig. 2.

The shell 0, that forms a bearing for the journal D, of an axle, is of the usual form, and is held from displacement by its engagement with transverse spaced shoulders f, formed on the inner face of the top wall of the box. and also by the cheek ribs j" interiorly formed on the sides of the box. The location of the shell 0, is such as to permit a proper space to intervene between the collar end of the journal D and the lid B of the box, as well as a suitable sponge holding cavity below the journal.

A preferred means to retain fibrous material in place at the front end and below the journal D, consists of a shoe E, which is easily insertible through the aperture that is normally closed by the lid B. As shown in Figs. 1, 2, 6 and 7, the shoe E, is provided with spaced ribs g, on its upper face which ribs are serrated on their upper edges, and as represented at g in Fig. 2, the front part of the shoe is curved upwardly to adapt it to conform with the curved front wall A of the box A, and also to render the ribs 9 capable of sustaining a mass of sponge at the front end of the journal D. Above the ribs g, at their front top edges, a vertical gate h, is adapted to slide, by its loose engagement with opposite guide grooves h, formed in the sides of the box A, which gate when in place, co-acts with the ribs 9 to retain the fibrous sponge material from displacement by affording .a reer ture is formed in the end wall for the free. insertion of the axle journal D,.and near to said end wall two parallel transverse slots are formed in the top wall of the box body. The slots 71 t" mentioned, are spaced apart by an intervening cross wall 7a which latter is apertured for the passage through it of the axle journal D. Another cross wall at is formed in the box A, at a proper distance forwardly of the transverse wall It and is similarly apl ertured for a like purpose. I

Within the space between the transverse walls 70 and at two similarslide plates n, are 1 loosely inserted; these plates have their .meeting edges at the transverse center of the box I A, and each has formed therein a semi-circular recess adapted to receive and to fit upon i one halfthe body of the axlejourna-l D, as represented in Fig. '5. The plates n, are pressed toward each other, by the spring frames 0 that are of like const-ruction, each beingcomj posed of two upright parallel bars provided with opposite spaced pins, whereon the spiral springs 0, are supported, these springs acting together to spread the pairs of barsf One bar of each frame engages the side wall 3 of the box A, and the otherbar presses against f theadjacent edge of the plate a, it is opposite; it being necessary that a sufficient width Q be given to the slot 2', wherein these parts are i loosely held, to allow them to be introduced and work as stated. I In the slot 11 next the rear wall of the box 5 body A, two nearly similar fiat gates p p,are l inserted loosely, which gates join each other; and have their meeting edges beveled inward-lya-nd downwardly and cut away to form f equal semi-circular recesses that together A form a circular aperture equal in diameter to that of the axle journal D. The impingingi edges of the gates 19 p, are in a horizontal j plane and therefore at a right angle to the 1 meeting edges of slide plates at. The lower slide gate 1) is upwardly pressed by the springs 19 that are sea-ted in pockets on the lower wall of the box A, near each side of the same, and the upper gatep is downwardly actuated by an elliptic spring 1", the latter having its ends in contact with the upper edge of the gate named, and its bowed center portion pressed upon by a cap piece 8. As shown, the cap piece 8 is sea-ted upon the top wall of the box body A, and is of-such aproportionate width and length as will allow it to cover the f upper edge of the gate 19, and ends of the; slide plates 12., these sliding pieces being adapted to play Within recesses in the cap piece which align respectively with the slots 2 t" in the top wall of the box. On each side wall of the box body A, at a f proper point to coincide with the end portions of the cap piece 8, lateral projections to, are formed near the upper side .of the box body,

the length of the capp'iece being suificient to cover these projections. There is a spring receiving channel transversely formed on the lower side of the cap piece 3, near each end, and a bowed springo, V

is secured at its bow in each channel, the depending end portions of said springsprojecting into the pockets 1; that are formed in pairs properly separated in the projectionsu, see Fig. 8. The lower end portions of the springs 1 are bent into locking knobs c that.

cap piece is forcibly pulled in an upward direction. V

The provision of the pairs of sliding plates and gates, as described, restrains the escape of any lubricating material at the inner side of the box A, when .in service, while the closely fitted lid '13, effects .a like service at the front of the axle box.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination, .with an axle box apertured at its forward end, of a hinged lid on said aperture, a detent disk I) havingascalloped periphery and aspr ing device adapted to snap into the scallopsand hold the lidclosed or at different points of open adjustmenh-sub- Z stantially as described.

2. The .cornbination, with an axle boxapertured at its forward end, and a lid jointed to the box over said aperture, of a ,pint'leloosely held in the joint scrolls, and cap plates se cured to the sides of the axle box over the ends of the pintle, substantially as described.
